Abstract:
Multi-tier architectures are now the standard for advanced information
systems. Replication is used to provide high-availability in such
architectures. Most existing approaches have focused on replication
within a single tier. For example there exist various approaches to
replicate CORBA or J2EE based middle-tiers, or the database tier.
However, in order to provide a high-available solution for the entire
system, all tiers must be replicated. In this paper we analyze what is
needed to couple two replicated tiers. Our focus is to analyze how to
use independent replication solutions, one for each tier, and adjust
them as little as possible to provide a global solution.IEEE Distributed Systems Online - Web
